THE PRESSURE GRADIENT BETWEEN THE SUBTROPICAL RIDGE OVER THE GULF
OF AMERICA AND LOWER PRESSURES IN THE DEEP TROPICS RESULT IN
FRESH TO STRONG NORTHERLY WINDS AND SEAS OF 6-9 FT IN THE GULF OF
TEHUANTEPEC. FARTHER WEST, A STRONG GALE CENTER NEAR CALIFORNIA
SUSTAINS A LARGE AREA OF NW SWELL THAT IS PRODUCING SEAS OF 6-9
FT NORTH OF PUNTA EUGENIA, ESPECIALLY WEST OF GUADALUPE ISLAND.
MEANWHILE, MODERATE TO FRESH NW WINDS AND MODERATE SEAS ARE
FOUND IN THE CENTRAL AND SOUTHERN GULF OF CALIFORNIA AND OFF BAJA
CALIFORNIA SUR. ELSEWHERE, MODERATE OR WEAKER WINDS AND SLIGHT
TO MODERATE SEAS PREVAIL.
FOR THE FORECAST, THE GRADIENT RELATED TO HIGH PRESSURE OVER THE
GULF OF AMERICA WILL CONTINUE TO INDUCE FRESH TO STRONG
NORTHERLY GAP WINDS IN THE GULF OF TEHUANTEPEC REGION THROUGH
SAT MORNING, THEN GRADUALLY DIMINISHING THROUGH SAT AFTERNOON AS
THE HIGH PRESSURE SLOWLY WEAKENS. SEAS IN THE GULF OF
TEHUANTEPEC WILL SLOWLY SUBSIDE THROUGH SAT. GALE CONDITIONS MAY
BE POSSIBLE IN THE GULF OF TEHUANTEPEC REGION TUE. NORTHWEST
SWELL PROPAGATING THROUGH THE WATERS NORTH OF PUNTA EUGENIA WILL
BE REINFORCED BY A NEW SET OF NORTHWEST SWELL BUILDING INTO THE
REGIONAL WATERS THROUGH TONIGHT, SPREADING ROUGH SEAS SOUTHWARD
ACROSS THE OFFSHORE WATERS OF THE BAJA CALIFORNIA PENINSULA
THROUGH THE UPCOMING WEEKEND. HIGH PRESSURE WILL BEGIN TO BUILD
ACROSS THE BAJA WATERS TONIGHT AND THROUGH THE UPCOMING WEEKEND
BRINGING A RETURN TO MORE TYPICAL NORTHERLY WINDS. FRESH TO
LOCALLY STRONG NORTHWEST WINDS ARE LIKELY TO DEVELOP IN THE GULF
OF CALIFORNIA SUN INTO TUE AS HIGH PRESSURE STRENGTHENS ACROSS
THE REGION.
